Today, San Francisco Mayor Newsom signed the final piece of legislation necessary to get the city’s PACE (municipal property tax financing for energy efficiency, renewables, and water conservation) program off the ground. My colleague Rosalind Jackson recorded the moment for posterity.

By summer, if all goes as scheduled, 70-80% of California will have access to a PACE program. That’s good news for property owners and the carbon cause.

Signficantly, most of the state’s PACE programs will require some sort of loading order — a certain level of energy efficiency first before you can do solar PV or solar thermal. This whole-building approach is going to require a greater level of integration between the solar and EE industries than currently exists. Business op!
